More to the point for us, as long as the natural gas comes in from ONG, we've
got heat. If we have heat, we can survive in the house, so it makes sense to
run a generator, and we might as well use the feed from ONG. No tanks, just
another pipe coming out of the ground or the house to the generator, on the
we-pay-for-it side of the gas meter.

We're 2 blocks away from the local ONG compressor station, which has its
own natural-gas-driven generators and pumps, so as long as there's gas
coming in to there, we'll have gas, too -- unless the pipes get cold enough
to liquefy the methane. That's very roughly -250F.

If we don't have gas, we won't have heat, either, except maybe for electric
space heaters, so it'll be time to open the taps to keep the pipes from
bursting and head for someplace that does have heat.
